IMPROVEMENT IN CHIMNEYS FOR LIM EKILNS.

Specification forming part of Letters Patent No. l I 1,874, datedFebruary 14, 1871.

To all whom it may concern:

Be it known that I, WILLIAM RENNYSON, of Norristown, in the county ofMontgomery, and in the State of Pennsylvania, have invented certain newand useful Improvements in Chimneys for Limekilns; and do hereby declarethat thetollowing is a full, clear, and exact description thereof,reference being bad to the accompanying drawing, and to the letters ofreference marked thereon, making a. part of this specification.

The nature of my invention consists in the construction and arrangementof a chimney for limekiln, as will be hereinafter more fully' set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents a perspective View of my improved chimney.

A represents the lower part of my chimney, made of suitable metal, inthe shape of an inverted funnel, and of such size as to fit over andcover the aperture at the top of a limekiln. From the apex of the funnelA a tube, B, leads upward for a suitable distance, and the upper end ofsaid tube is provided with a cap, U, from the center of which a rod, D,extends upward and connects with a lever, E. This lever is pivoted to anarm, G, projecting from the tube B, and a cord or rod, a, is attached tothe other or outer end of said lever, by the use of which the cap 0 maybe raised up from or put on the tube B.

On the sides of the funnel-shaped base A are handles b b, so that thechimney may be easily lifted off when so desired.

ing the coal.

The object of my invention is to secure the entire control of kilnsduring the production of lime.

Ordinary limekilns are open on top and frequently very troublesome,sometimes burning the stone almost to cinder, and at others just burningthe outside, leaving the balance unburned.

My chimney or top placed upon any kiln will make a strong draft, and,consequently, a strong fire. The cap or damper on top can be used inregulating it; or, when the damper is closed, the fire can be heldwithout consum- I intend them very heavy, and also so light that two orthree men can pick them up and carry them from kilns without muchtrouble. I intend to make them all in one piece, with handles, so thatmen can get hold of them and move them without any difficulty, or haveframe or skeleton standing with doors arranged on hinges, or made to fitso as tomake the top air-tight.

- Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, ist The combination of thefunnel-shaped base A, tube B, and cup or damper O, with its operatingmechanism, all constructed. arranged, and operating substantially asshown and described, and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this5th day of January, 1871.

WILLIAM RENNYSON.
